' Application filed July 26,

This invention relates to bumpers for vehiclesand itsprimary object isto provide a bumper of the spring type and one which possesses greatstrength as well as adds materially to the ornamental appearance of vthe vehicleto which the bumper is attached.

Another object of, the'invent ion is to provide a bumper which not onlypossesses great strength at its striking portions, but is so formed toeliminate; or reduce damage to a minimum, regardless of the forceofimpact with an obstructing object.

. This invention also consists of certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, il-

lustrated in the accompanying drawings, andspecifically pointed out inthe appended In describing my invention in detail, reference will be hadto the accompanying drawings, wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a front elevation of a motor vehicle, showing one form ofmyv novel bumper associated therewith.-

Figure 2 is a sectional view taken on 2 2 of Figure 1. I

Figure 3 is a top plan view of a fragmentary portion of the bumper shownin Figure 1.

Figure 4 is a front elevation of a modified form of bumper.

Figure 5 is a similar view of another modified form.

Figure 6 is a top plan view of the modified form as shown in Figure 5.

Referring to the drawings in detail, the letter A indicates the front ofa motor vehicle which has one form of the bumper which forms the subjectmatter of the present invention associated therewith, and it will beobvious that either form of the bumper as shown in the drawings can besecured to the front or the rear of the vehicle, without departing fromthe spirit of the invention.

The bars of the form of bumper as shown in Figures 1- to 3, inclusive,are indicated by the reference numerals 1, 2 and 3, respectively, andare arranged in edge to edge superimposed relation, with the endsthereof curved slightly rearwardly and terminating in bearings whichsurround the bolts 4 and 5 in spaced relation with respect to each line1926.

other. The bolts 4 and 5 are suitable nutsf (not shown) The centralportion of'eachbar l, 2 and 3 is twisted in'auger formation to addmateprovided with rially to the strength. thereof, withoutdeparting'from the resiliency of the bars, and arranged upon oppositesides of the twisted portions of the-bars are clamps 6 'which includefront plates 7r11aving their upper ends bent upon themselves to providehook flanges 8 including confronting ends 9 WlllCh engage'the recessedend portions 10 of the rear plates 11, as shown in Figure 2.

The rear plates 11 are centrally recessed as at 12 to accommodateone-end of the curved strips. 13 which have their opposite ends'bifurcated'to provide arms 14 and. 15 having tlieir ends carried uponthemselves to form bearmgs 16 which are secured to the bolts 3 and .46between the bearings ofthe bars'and provide spacers therefor, as shownin Figure 1. The respective plates of the clamps are seoured'together bybolt and nut connections 17. The strips 13 are adapted to be secured tothe frame of the vehicle by suitable brackets (not shown).

In the modified form, as shown in Figure 4:, the bars 19 also have theirintermediate portions twisted into auger formation and the longitudinaledges of the bars 19 upon opposite sides of the twisted portions thereofare bent in confronting relation as at 20, while the ends of the bars'19 are integrally formed with enlarged bearings through which pass thebolts 21 provided with suitable heads as shown.

In the modified form, as shown in Fig-- ures 5 and 6, the bars 22 areclamped together in the same manner as the bars 1, 2 and 3 in the formfirst described, but in this instance a single clamp 23 similar to clamp6 is used and is disposed between the twisted portions of the bars 22and centrally of the respective bars as clearly shown v in Figure 5 ofthe drawings. The. upper "1 bar of the bars 22 is provided at each 6 endof the clamp with a single twist, the middle bar with a double twist,and the lower bar with a triple twist. The ends of the bars 22 arecurved upon themselves to provide the bearings 24 surrounding the bolts25, as shown in Figure 6, and the rear bar 27 is formed with bifurcatedends to provide arms 28 which have their ends curved upon themselves toform bearings .tion thatthe advantages andnovel features of my inventionWlllilOG readilyiapparent.

I desire .it to be :understood that I may make changes in theconstruction and in the combination and =-arr.angem-ent of the severalparts, provided Ftllitt such changes ;fall within the-scope 'ofstheappended claims.

,Having' thus described'my invention, what is claimed is: I

'1. A .bumper'ofthe character described comprising spaced superimposedbars Zlraving portions twisted into auger form.

2. A bumper-of-the character described. comprising bars :having portionsthereof twisted into auger iform'. said bars having their ends bent uponthemselves to provide bearings, and ;means passing 1 through said:bearings 'for Lretaining 'and securing said bars in superimposedrelation.

3. A bumper of thecharacter described.

comprising bars arranged in superimposed relation, and having portionstwisted into auger formation, clamps .for retaining said bars insaidsuperimposed relation and including front plates having flanged ends,recessed rear plates having recessed ends ,i'or receiving the flangedends, bolts for securing said plates in cooperative position .r aboutsaidabars strips having one of their ends curved upon themselves andclamped :in' theare'cess ofithere'ar plate ,of the clamps, bearingsformed iOn'tlle :ends of said bars rand =1tl1e strips, respectively,"and bolts 113E188- through said bearings.

4:. A bumper of the character described.

comprising bars arranged sinrsuperimposed I relation, twistedportionscformed in. each bar, bearings formed'on the ends of .said.

lbars, ineans' for clamping said bars in their superimposedrelation,means @passing through the bearings forseeuring the bars in cooperativeposition, bifurcated-means having bearings formed on the arms of thebifurcated portions thereof and disposed be- :tween the bearings=ofzthebars to provide pacers therefor, and. :said means being clampedin :the clamping means. v Intestimony whereof I-afiiximy signature.
